HEADLIGHT.

Specification 0! Letters Patent. Patented J an. 30,1917,

Application filed July 26, 1913. Serial No. 781,361.

To all whom it may concern:

Be it known that we, EDWARD L. J ILLSON and WILLARD R. J rnLsoN, J r., citizens of the United States, and residents of Syracuse in the county of Onondaga and State of flew York have invented a certain new and usehu lleadlight, of which the following is a specification.

This invention relates to head lights particularly applicable to motor vehicles, and has for its object means by which the light can be dimmed and the direction thereof changed; and the invention consists in the novel combinations and constructions hereinafter set forth and claimed.

In. describing this invention reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure l is a horizontal cross-sectional view through a head light embodying our invention. Fig. 2 is a vertical sectional view thereof. Fig. 3 is an enlarged sectional view through the steering knuckle of the motor vehicle. Fig. 4: is a diagram of the electrical connections.

This invention includes a head light comprising a reflector, a main lamp located in the focal axis of the reflector, and a supplemental lamp located at one side of said focal axis, and means for controlling the lighting of the lamps.

l is the casing of the lamp, 2 is the lens -or glass front, 3' is the reflector which may be of any suitable curvature to normally focus the rays oflight from a centrally located lamp so that the rays are projected forwardly in substantial parallelism.

4 is the main lamp which is an electric lamp, the main lamp being located in th focal axis of the reflector 3.

We have here shown my head light as having a plurality of supplemental, electric lamps located out of the focal axis of the reflector, these supplemental lamps being located respectively to direct. the light for wardly and downwardly, to the right, and to the left. J

and 6 and 7 are other supplemental lamps arranged to the left and right of the main lamp in position to direct the light to the right and to the left with respect to a person seated in the vehicle. Preferably additional reflectors 8 are provided for the lamps 5, 6 and 7, the reflectors 8 being arranged with their focal axes at an angleto the focal axis of the reflector 3. These reflectors 8 are preferably part of the main reflector and are facets or depressions pro-- vided on the main reflector.

The lamps 4, 6, 7 are incandescent lamps which are lighted from the usual storage battery with which motor cars are now almost universally provided, and in use when the car is traveling straight ahead-the main lamp 4 only is lighted, but when it is necessary to dim the. light, the lamp 4 is extinguished and the lamp 5 lighted and when the lamps 4 or 5 are lighted and the car is turned to either the right or the left, one or the other of the lamps 6"and 7 is lighted when the'car has turned a predetermined distance and when one or the other lamps 6 and 7 is lighted the lamp 4 or 5 is extinguished. p p

The lighting of the lamps is controlled by the steering means of the motor vehicle and I have here shown the lighting of the lamps as controlled from the steering knuckle, the movable section 9 of which carries one member of a switch and the fixed section 93 carries another member of a switch, one member of the switch being a single arm or contact connected in one leg of the main circuit and the other member of the switch having contact surfaces and terminals connected to branches of the. other leg of the main circuit which branches are. A

connected in a circuit with the lamps 4 or .rcircuit' respectively with the. lamps 4 or 5,

5 designates the supplemental lamp "lo-\ijand 7 the :middle contact surface 11 becated above the mainvlamp 4 in position to direct the light-forwardly and downwardly;

mg Y of considerable length to permit the lamp 4 or 5 to remain lighted until the steering wheels have been turned through a comparatively long arc. The turning on of the lamps is controlled by a suitable switch 1 arranged on the dash board of the vehicle.

15 is the battery, 16 the leg connecting one side of the battery and the switch arm 10; 17 is the leg leading from the other side of the battery and connected to switch contacts 18 and 19.

20 is the branch of leg 17 connected to the lamp 4:, and 21 is a conductor in the branch 20 which conductor 21 connects the lamp 4: and the contact surface 11 of the fixed member of the switch on the steering knuckle. The conductor 2Q is also connected to the switch contact 22 with which the main switch 14 engages. 23 is another branch of the leg 17, which branch 23 is connected to the upper lamp 5, and 24; is a conductor connecting said upper lamp 5 and the contact 11. The conductor 23 is connected to another switch contact 25 with which the switch 14 engages. 26 is the third branch of the leg 17 which branch, is connected to the switch contact points 18 and 19 and is itself branched and the branches 2? and 28 thereof connected respectively to the lamps 6, 7. Said lamps 6, 7 are connected respectively by conductors 29 and 30 to the contacts 12 and 13 of the fixed member of the switch of the steering knuckle.

The switch 14 is manually operated and when shifted to connect the points 18 and 22, the main lamp 4; will be lighted except when the steering knuckle turns sufficiently to engage the switch arm 10 thereof with either the contact surfaces 12 or 13 when one or the other of the lamps 6, 7, as the case may be, will'be lighted. When the switch is shifted to connect the terminals 19 and 25, the supplemental lamp 5 will be lighted instead of the main lamp a when the car is traveling straight ahead, and the other supplemental lights 6, 7 will be lighted when the steering knuckle turns sufliciently in one direction or the other.

What we claim is 1. The combination of a head light having a main reflector,-the reflector having a facet above the focal axis of the reflector,

and arranged with its focal axis at an angle to the focal axis of the reflector and hence constituting an additional reflector, a main lamp arranged in the focal axis of the main reflector and a supplemental lamp arranged in the focal axis of the facet, and means for controlling the lighting of the lamps, substantially as and for the purpose set forth.

2. The combination of a head light having a reflector formed with facets on opposite sides of the focal axis of the reflector and arranged with their focal axes at an angle to the focal axis of the reflector, a main lamp arranged in the focal axis of the renaiasoe flector and supplemental lamps arranged in the focal axes of the facets, and means for controlling the lighting of the lamps, substantially as and for the purpose described.

3. The combination of a head light having a main reflector provided with facets on opposite sides of and above the focal axis of the reflector, each facet being arranged with its focal axis at an angle to the focal axis of main reflector and thereby constituting an additional reflector, a main lamp arranged in the focal axis of the main reflector, and supplemental lamps arranged in the focal axes of said facets, and means for controlling the lighting of the lamps, substantially as and for the purpose specified.

t. The combination with the steering means of a motor vehicle; of a head light having a main reflector provided with additional reflectors on opposite sides of the focal axis of the main reflector, the additional reflector being arranged with their focal axes at an angle to the focal axis of the main reflector in order to direct the light to the right and left respectively, electric lamps in the focal axes of the reflectors respectively, and an electric lighting circuit having a switch thereinincluding two members, one being carried by a movable part of the steering means and the other being fixed and provided with three contact surfaces, one leg of the circuit being connected to one of the members of the switch and the other leg being divided into three branches in which the lamps are connected,

the branches being connected respectively to said contact surfaces, substantially as and for the purpose described.

5. The combination of a head light having a main reflector, the reflector having a facet above the local axis of the reflector, a main lamp arranged in the focal axis of the main reflector and a supplemental lamp arranged in the focal axis of the facet, and means for controlling the lighting of the lamps.

6. The combination of a head light having a reflector formed with facets on opposite sides of the focal axis of the reflector, a main lamp arranged in the focal axis of the reflector and supplemental lamps arranged in the focal axes of the facets, and means for controlling the lighting of the lamps.

7. The combination with a main reflector and a lamp focusable in relation thereto, of an auxiliary lamp arranged in a niche in said reflector.

8. A parabolic'lamp reflector having a niche or depression in a portion of its wall forming an auxiliary reflector, an auxiliary lamp in said niche,'and a main lamp focusable in relation to said parabolic reflector.

9. A lamp reflector, having its walls fashioned for the focusing of a main lamp, and
